Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for open-source model APIs. The default in this space.
